Atleast its not 2010-2013 all over again.
Dammit Vettel.
Err... I don't mean to sound rude but did you even follow those seasons?
2010 had four genuine title contenders at the last round of the championship, and Vettel was the least likely to win, the entire season it was either Alonso, Webber, or Hamilton that people were talking about.
2011 Red Bull were a cut above with their ebd, and Vettel adapted to the new driving style required for the ebd cars much quicker than Webber, and dominated the season. The only season he truly dominated.
2012 had 7 different winners for the first 7 races. Red Bull and Mclaren were about on par with each other, but both had reliability issues, allowing the slower, but far more reliable Ferrari, of Alonso, to stay in the title hunt until the final race. Actually leading the championship for much of the year.
2013 Mercedes had the quickest car by a significant margin, but horrendous tire overheating problems, coupled with that year's extremely fragile tyres in the first half of the season, saw them lock out the front row in quali, and end up often outside the top ten in the race. Ferrari nailed the fragile tyres, and Alonso took two wins early in the season, and was looking good. Tyres were changed mid-season due to safety issues following the British GP, which suddenly saw Ferrari with huge tyre warm up issues, unable to turn them on. Red Bull and Mercedes were perfectly suited to the new construction, but Vettel proved again why he was three time champion, winning every race in the second half of the season.
I don't see that period as anywhere near as dominant or predictable as we are currently witnessing with Mercedes.
2014, Mercedes locks out the front row almost every race. Ricciardo being the only non-mercedes driver to win a race, and only three times, when Mercedes had problems.
2015 so far, Mercedes has won every race except one race where Vettel stunned everyone in Malaysia to win a genuine on track race against them. Since then Mercedes has locked out the front row every race and won every race.
